I've used this program for the two years (current date 9/2018) since I got a new printer. Seemed like a great idea. I have two kids in middle/high school, I feel like I print things pretty regularly, so does my husband. Having looked over our usage, we generally print just over 100 pages per month. That means the 100 page per month is too small and the 300 pages per month is WAY more than we need. But I was paying for the 300 page per month plan. Today I decided to go look at the cost of ink to see if I was really saving anything. At the first place I checked, I found that the cost of the black XL and multi pack color was just over $100 (I was paying about $120/year for the instant ink program, and yes, I realize they're supposed to be bigger cartridges). Please note that I have been enrolled in the program for 2 years (a few of those months were on the smaller plan, but for the purposes of my review, let's just figure $120/year for 2 years). I decided to cancel my plan. Here's what I found interesting about the cancellation process...I got an email telling me that the cartridges that I'd been sent from the instant ink program would no longer work after my cancellation date and I should send them back for recycling. Part of the agreement, blah, blah, blah. OK, fine. I'd gotten a box of cartridges back in April of this year, but it was unopened as I hadn't needed them yet. Over the 2 year period, I've paid for what amounts for 2 "sets" of ink, but only used one. Presuming that the cartridges in my printer are nearly empty (since they sent me new ones 5 months ago), I've paid over double what I would otherwise have paid for the ink I've used. Very disappointing. Very not impressed with this program, which, at the moment, I'm feeling like is a rip off. I'm sure it was in the small print, but when I signed up and as I've been going along, it never occurred to me that the cartridges provided were any different than the ones I could buy anywhere. I thought it was just an ink subscription service. I would not recommend the program at this point, for any level of printing. The idea of not having to go run out to get ink is nice, but I'm not willing to pay what will end up being more than double the standard price for the convenience of "never running out of ink". I can never run out of ink by buying an extra set of cartridges and keeping them on the shelf near my printer.
